DC204TM thread milling cutter — for S12, S14, S21, S30 and S40 indexable inserts, Ø14.5 mm (Teknik Makina)

The DC204TM thread milling cutter is a precision tool intended for machining internal and external threads with indexable inserts across several standard sizes, offering quick insert changes and predictable cycle times

• Compatible with S12–S40 indexable inserts
• Cutting diameter Ø14.5 mm
• 20 mm shank for secure clamping
• M2.5x7 Torx screw, T8 key included

Consistent thread quality through precise geometry

The cutter’s design prioritises repeatability and dimensional control: the combination of a defined cutting diameter and exchangeable indexable inserts ensures threads are produced with uniform pitch and profile. By using a standardised insert range, the tool reduces variability between setups and lowers scrap rates, which supports stable production runs and predictable process capability. This focus on precision is particularly valuable where tight tolerances and reproducibility are required.

Secure clamping for vibration-resistant machining

A 20 mm shank provides a robust connection to the toolholder, improving stiffness and reducing deflection during threading operations. Together with a carefully considered overall length of 85 mm, the assembly minimises chatter and enhances surface finish, especially on interrupted cuts. The inclusion of an M2.5x7 Torx screw and T8 key simplifies insert retention and replacement, shortening maintenance intervals and lowering machine downtime while maintaining consistent cutting conditions.

Streamlined workshop logistics and faster set-up

Compatibility with a broad range of insert sizes (S12, S14, S21, S30 and S40) allows the same cutter body to be used across different job types, reducing the need for multiple dedicated tools and simplifying inventory. This modular approach supports efficient workshop planning: fewer tool holders and insert types are required, which shortens setup times and accelerates job changeovers. The result is a tangible efficiency gain in batch production and mixed‑model environments.

Practical service life and maintenance advantages

The tool’s use of indexable inserts means wear is managed by replacing only the cutting edges rather than the entire cutter, which is cost-effective for medium to high volumes. Routine servicing is straightforward thanks to standard fasteners and the universal T8 drive, enabling trained staff to carry out secure insert changes quickly. Supplied by Teknik Makina, the cutter aligns with established industrial standards for robustness and repeatable performance, supporting dependable operation on CNC milling or turning centres.

FAQ

Which insert sizes can be used with this cutter?
The cutter accepts a range of indexable inserts (S12, S14, S21, S30 and S40), allowing flexible selection depending on thread form and cutting conditions.

What are the critical dimensions for toolholder selection?
Key dimensions are a 20 mm shank and an overall length of 85 mm; these values determine holder compatibility and required clearance.

How is the insert secured and replaced?
Inserts are fixed with an M2.5x7 Torx screw; replacement uses a T8 key, facilitating quick and repeatable changes.

Is this cutter suitable for heavy‑duty threading?
The combination of a 20 mm shank and standardised inserts provides good stiffness for typical industrial threading tasks; final suitability depends on the specific workpiece and machine setup.
